Nkhani - Kodi Ubwino wa Ma Wavelengths Aatali Amagalimoto a LiDAR Ndi Chiyani?

Lembetsani ku Social Media Yathu Kuti Mupeze Nkhani Yachangu

Kuyerekeza Kosavuta pakati pa 905nm ndi 1.5μm LiDAR

Tiyeni tichepetse ndikufotokozera bwino kufananiza pakati pa machitidwe a 905nm ndi 1550/1535nm LiDAR:

Mbali	905nm LiDAR	1550/1535nm LiDAR
Chitetezo cha Maso	- Yotetezeka koma yokhala ndi malire pa mphamvu kuti ikhale yotetezeka.	- Yotetezeka kwambiri, imalola kugwiritsa ntchito mphamvu zambiri.
Malo ozungulira	- Zitha kukhala ndi malo ochepa chifukwa cha chitetezo.	- Imatha kugwiritsa ntchito mphamvu zambiri mosavuta chifukwa imatha kugwiritsa ntchito mphamvu zambiri.
Kuchita bwino mu Nyengo	- Zimakhudzidwa kwambiri ndi kuwala kwa dzuwa ndi nyengo.	- Imagwira ntchito bwino nyengo yoipa ndipo sikhudzidwa kwambiri ndi kuwala kwa dzuwa.
Mtengo	- Zotsika mtengo, zigawo zake ndizofala kwambiri.	- Yokwera mtengo kwambiri, imagwiritsa ntchito zida zapadera.
Zabwino Kwambiri Zogwiritsidwa Ntchito	- Mapulogalamu ofunikira mtengo komanso zosowa zochepa.	- Kugwiritsa ntchito magalimoto apamwamba monga kuyendetsa galimoto yodziyendetsa yokha kumafuna mtunda wautali komanso chitetezo.

Kuyerekeza pakati pa makina a 1550/1535nm ndi 905nm LiDAR kukuwonetsa zabwino zingapo zogwiritsira ntchito ukadaulo wautali wa wavelength (1550/1535nm), makamaka pankhani ya chitetezo, mtunda, ndi magwiridwe antchito m'malo osiyanasiyana. Zabwino izi zimapangitsa makina a 1550/1535nm LiDAR kukhala oyenera kwambiri pakugwiritsa ntchito komwe kumafuna kulondola kwambiri komanso kudalirika, monga kuyendetsa pawokha. Nayi tsatanetsatane wa zabwino izi:

1. Chitetezo Chowonjezera cha Maso

Ubwino waukulu wa makina a 1550/1535nm LiDAR ndi chitetezo chawo champhamvu kwa maso a anthu. Mafunde ataliatali amagwera m'gulu lomwe limayamwa bwino kwambiri ndi cornea ndi lenzi ya diso, zomwe zimalepheretsa kuwala kufika pa retina yodziwika bwino. Khalidweli limalola makinawa kugwira ntchito pamlingo wapamwamba kwambiri pamene akukhala mkati mwa malire otetezeka, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito makina a LiDAR ogwira ntchito bwino popanda kuwononga chitetezo cha anthu.

DALL·E 2024-03-15 14.29.10 - Pangani chithunzi chosonyeza malo a msewu kuchokera ku mawonekedwe a makina a LiDAR a galimoto, ndikugogomezera kapangidwe kake ndi mapangidwe a msewu monga

2. Kuzindikira Kwautali

Chifukwa cha kuthekera kotulutsa mphamvu zambiri mosatekeseka, makina a 1550/1535nm LiDAR amatha kupeza nthawi yayitali yodziwira zinthu. Izi ndizofunikira kwambiri pamagalimoto odziyendetsa okha, omwe amafunika kuzindikira zinthu patali kuti apange zisankho panthawi yake. Kutalikirana kwa kutalika komwe kumaperekedwa ndi mafunde awa kumatsimikizira kuthekera kwabwino koyembekezera ndi kuchitapo kanthu, zomwe zimawonjezera chitetezo chonse komanso magwiridwe antchito a makina odziyendetsa okha.

Kuyerekeza kwa Lidar pakati pa 905nm ndi 1550nm

3. Kugwira Ntchito Kwabwino Panyengo Yoipa

Makina a LiDAR omwe amagwira ntchito pa mafunde a 1550/1535nm amasonyeza bwino ntchito yawo pa nyengo yoipa, monga chifunga, mvula, kapena fumbi. Mafunde ataliatali awa amatha kulowa mu tinthu ta mlengalenga bwino kwambiri kuposa mafunde afupiafupi, kusunga magwiridwe antchito ndi kudalirika pamene mawonekedwe awo ndi otsika. Mphamvu imeneyi ndi yofunika kwambiri kuti makina odziyimira pawokha azigwira ntchito nthawi zonse, mosasamala kanthu za momwe zinthu zilili.

4. Kuchepetsa Kusokoneza kwa Dzuwa ndi Magwero Ena a Kuwala

Ubwino wina wa 1550/1535nm LiDAR ndi kuchepa kwa mphamvu yake yokhudzana ndi kusokonezedwa ndi kuwala kozungulira, kuphatikizapo kuwala kwa dzuwa. Mafunde enieni omwe amagwiritsidwa ntchito ndi makinawa sapezeka kawirikawiri m'magwero achilengedwe ndi opanga kuwala, zomwe zimachepetsa chiopsezo cha kusokonezedwa komwe kungakhudze kulondola kwa mapu a chilengedwe a LiDAR. Mbali imeneyi ndi yofunika kwambiri pazochitika zomwe kuzindikira ndi kupanga mapu molondola ndikofunikira.

5. Kulowa kwa Zinthu

Ngakhale si chinthu chofunikira kuganizira pa ntchito zonse, kutalika kwa mafunde a 1550/1535nm LiDAR systems kungapereke kuyanjana kosiyana pang'ono ndi zipangizo zina, zomwe zingapereke ubwino pazochitika zinazake zomwe kuwala kolowera kudzera mu tinthu tating'onoting'ono kapena pamwamba (mpaka pamlingo winawake) kungakhale kopindulitsa.

Ngakhale zabwino zonsezi, kusankha pakati pa makina a 1550/1535nm ndi 905nm LiDAR kumaphatikizaponso kuganizira za mtengo ndi zofunikira pakugwiritsa ntchito. Ngakhale makina a 1550/1535nm amapereka magwiridwe antchito abwino komanso chitetezo, nthawi zambiri amakhala okwera mtengo chifukwa cha zovuta komanso kuchuluka kochepa kwa zinthu zomwe amapanga. Chifukwa chake, chisankho chogwiritsa ntchito ukadaulo wa 1550/1535nm LiDAR nthawi zambiri chimadalira zosowa zenizeni za makinawo, kuphatikiza kuchuluka kofunikira, kuganizira za chitetezo, momwe zinthu zilili, komanso malire a bajeti.
